Symbolic Link

The point of this is to make it easy to update your client machines to newer versions of CentOS when they are released. In the client configuration files above, the baseurl points to the symbolic link location.

When CentOS 7.3.xxxx is released, after downloading a building the new repository, all that is required is for you to delete and re-create the symbolic link.

The client .repo files don't need to be updated, all you need to do is run yum update and your CentOS machine will install all the newer client packages.
